Coal gasification experiment was conducted with high ash fusion temperature coal in an entrained flow gasifire to evaluate the dry-ash removal process. In the conventional entrained type coal gasification process, coal ash was removed as the molten slug at the bottom of gasifier. Therefore, comparatively low fusion ash temperature coal was usually used in these gasification processes. However, it is very important to use the high ash fusion temperature coal in the coal gasification process in the near future to achieve the high power generation efficiency. From these reasons, new gasification process with high ash fusion temperature was proposed and gasification experiment was conducted In the proposed process, the ash was removed without melting. Therefore, the gasification condition on each coal characteristics was very important In this study, the gasification experiment with different operation condition, such as (Vcoal, was conducted with different types of coaL To evaluate the gasification performance and ash behavior, produced gas composition was measured and recovered ash after the gasification experiment was analyzed.
